AIR.\VASHER FOR INTERll'AL-COMBUSTION NG-INES.

m1-cation flied september 21, 192e. semi No. 136,885. p

rlhis invention aims to provide novel means whereby air may be washed and liltered before it is delivered to the carburetor ot' an internal combustion engine.

1t is within the province ot the disclosure to improve generally and to enhance the utility ot devices ofthat type to which the invention appertains. Y

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in theeombination and` arrangement ot parts and in the details ot construction hereinafter described and claimed., Ait being understood that changes in the precise embodiment of the invention herein disclosed, may be made within thescope ot what is claimed, without departing trom the spirit oit the invention.r Y

ln the drawings Y v Figure 1 showsin elevation, a portion of an internal combustion engine'whereunto the device forming the subject matter of 'his application has been applied, parts ap-A pearing in section;

Figure 2 is a longitudinal section ot the attach ment j;

Figure 8 is a cross section on the line 3-8 of Figure 2;

Figure e is a cross section on the line 4-fl of Figure 2.

In Figure 1 of the drawings, there visl shown an internal combustion engine provided with a carburetor 1. The radiator extension is shown at 2, and the numeral 3 designates the oyer-iow pipe for the radiator. rllhe securing elements which hold the cylinder head -on the engine block are marked by the numeral 4l.

In carrying out the invention, there is provided a plate-like bracket 5 which is held byv the securing elements lon the trame work ot' the engine, the bracket 5 including a `ring 6 within which entends the tubular body 7 ot a receptacle 8, the receptacle in cluding a. lid 9 mounted on the body 7. The body 7 is provided near to its lower end with a circumferential stop bead 39 against which abuts the cup-like bottom or the receptacle 8, the bottom 10 having a stem 11 received slidably in a guide strip 12 that is extended across the body 7, thenpper end of the stem 11 being threaded into a bridge 14 which extends across the body 7. The body 7 has trunnions 15 mounted to rockin the ring 6, and enabling the receptacle 8 to be adjusted in position, to accommodate itself readily to certain lues and pipes, for instance, to an air liuc 16, the lower end of which is connected to the air intake oit the carburetor, the' upper end .ot the air flue 16 being connected to an elbow 17 that mounted onthe lid 9. y f

n the upper end of the receptacle 8 there is located a distributing` head 18, preferably in the `form oi a perforated coil, voneV end ot' the coil extending outwardly through the lid 9, the said end ot' the coil being secured in the lid 9. Y One end ot a tube 19 is mounted on the exposed portion of the coil 18, the other end oi' the tube 19being connectedto a nipple 20 which is mounted Ain the radiator extension 2, the voveriiow pipe 3 being shortened enough so that there is a vapor Y l extension 2, above the level of the water in the radiator. The coil or distributor head 18 preferably is open at its lower end. V

A cup 21 is mounted on the elbow 17 and carries a valve mechanism 22 which limits the flow of liquid out of the cup 21. Screens 23 are mounted removably in the body 7 ot the receptacle 8, belowthe distributing` head or coil 18. Filtering material ot any desired sort, marked by the numeral 24, is disposed between the screens 23.

The body 7 of the receptacle 8 is supplied with a lateral air'inlet pipe 25, the outer end ot the inlet pipe being covered by a .screen 26. The air inlet pipe 25 discharges into an inverted trough-shaped apron 27 carried by the side wall of the body 7 of the receptacle, the apron 27 having a delecting end wall 28 which is inclined a little with respect to the vertical.

Air enters the inlet through the screen 26, and the screen 26 picks out the very coarse matter which may be inthe air. The air is deiiected downwardly by the part 28 and is directed against a mixture of oils 29 Vwhich is carried by the cupelike bottom 10.

Vrlhe cup 21 contains turpentine or some other substance which aids in keeping down carbon. The turpentine or other liquid in the cup 21, drops downwardly into the filtering material at 24. Owing to the :tact that the distributing head 18 `is in the form of a coil, the turpentine or other material may drop downwardly from the cup 21-into the filtering material 24:, without fouling the distributing head 18 and clos-ing the openings or perforations in the said head.v In view of the fact that the turpentine or other material is discharged as aforesaid upon-the lter 24, vthe air is charged with the contents ont the cup 21, as the air passes upwardly through the filtering material 24. In the space 32 which exists above the uppermost screen 23, the air comes Lintol contact with vapor from the radiator, the vapor passing from the vapor chamber 31, throughthe tube 19,V and being distributed by the coi-l 18, in the space Shown at 32, the vapor passing outwardly through the perforations ot `the coil 18.

The air, deprived of dust, charged with vapor, and carrying some of the material from the cup 21, moves through the lue 15, and enters the carburetor 1, the performance ot the engine being improved accordingly.

Vhat is claimed is1- 1. In a device of the class described, a receptacle provided at its upper end with anair outlet, and supplied near to its'lower end with an air inlet, a iilter in `the receptacle between the inlet and the outlet, a disytributing head 4,in the receptacle above the filter, means for supplying vapor to the Vhead, vand a liquid container discharging downwardly on fthe filter, the head being centrally opened so that the container can 4discharge downwardly therethrough.

2. In a device of the class described, a receptacle -providedat its upper end with Tan air outlet, and supplied vnear to its 'lower end ywith anzair inlet", a fil-ter inthe recep tacle between the vinlet-and the'outlet, a distributing head in the receptacle Yabove the filter, means for supplyingvapor ,to the head, and a detachable cup-'like `bottom tor the receptacle, the air inlet embodying a YHector `for ldirecting the incoming air into the cup-like bottom.

n la device Vof the class described, af

a detachable cub-like bottomY and the air x 7 inlet embodying' ya fpdetlector Vfor directing the incoming air into the'cup-lilre bottom.

In testimony that I claim thetoregoing as my own, I have hereto aixed my signature.

EARL V, MORRS.
